<p>Hello everyone! I am a student who enjoys programming and Rust.<br>
Now to the main reason I'm here: There is a feature in nightly that I am interested but it seems like it has gone silent on github for a few months now. <code>Implement the feature</code> is done but not <code>Stabilization PR</code></p>
<p>So I am wondering if any of you can guide me to the proper channel where I can ask about it and possibly do it my self. (I have not touched rust internals before but the instructions seem simple enough)</p>
<p>Edit: I assume <a class="stream" data-stream-id="182449" href="/#narrow/stream/182449-t-compiler.2Fhelp">#t-compiler/help</a> might be the right place for this?</p>

<p>Hello <span class="user-mention" data-user-id="364100">@Spyros</span>. What feature do you want on stable? Does it seem like there are any things blocking stabilization when you skim the tracking issue?</p>

<p>The right place depends on what kind of feature it is, but I would guess it would be either <a class="stream" data-stream-id="213817" href="/#narrow/stream/213817-t-lang">#t-lang</a> or <a class="stream" data-stream-id="219381" href="/#narrow/stream/219381-t-libs">#t-libs</a>. In many cases it is not the compiler team that decides to stabilize a feature.</p>

<p>This is the issue: <a href="https://github.com/rust-lang/rust/issues/74217">https://github.com/rust-lang/rust/issues/74217</a><br>
It seems like there has been zero conversation on the topic so so nothing's blocking it. It seems like it's forgotten mostly and someone needs to do the stabilization pr</p>

<p>You could try to comment on the issue that you would like it to be stabilized and see if you get a response within a few days. If not, you should ask in <a class="stream" data-stream-id="219381" href="/#narrow/stream/219381-t-libs">#t-libs</a>.</p>

<p><span class="user-mention" data-user-id="364100">@Spyros</span> Another option would be to send that stabilization PR: A PR that changes the <code>unstable</code> attribute to <code>stable</code> on those functions. Looks like there's not much to discuss for this feature.</p>

<p>This was my first thought but since I haven't done it before I asked on a Rust related server on discord and people basically told me to ask here first so hopefully people could tell me what's is left to do.</p>

<p>The <code>stable</code> attribute wants a rust version. The bump to 1.50.0 is happening <em>right now</em>, so you can use <code>since = "1.50.0"</code> there.</p>

<p>I asked <span class="user-mention" data-user-id="121055">@Pietro Albini</span> to add a role for the libs team on the discord server so it'd be easier to know who to ask these things, but apparently those team roles are going away.</p>

<p>Hey people, not sure if I should make a new thread for this but in any case, things were not exactly the same as in <a href="https://rustc-dev-guide.rust-lang.org/stabilization_guide.html#stabilization-pr">https://rustc-dev-guide.rust-lang.org/stabilization_guide.html#stabilization-pr</a> though I think I did what was necessary. <br>
My question is: How can I test it?<br>
Is running <code>x.py test</code> enough?</p>

<p>Hi everyone,  <br>
I have been thinking for a while of a way to speedup generic compile time (okay, my thought were mostly for C++ but I don't see why they wouldn't apply to Rust too). Before trying to  implement anything I would have liked to get some feedbacks on that, do you think this is possible here? (Maybe it's a stupid idea after all!)</p>

<p>Hi everyone, <br>
Is anyone here familiar with the inner workings of rust-analyzer?  I'm trying to figure out how to query a crate for its public declarations.  I've spent some time combing through the source of hir &amp; hir_def, and I've gotten as far as getting a set of crate id's for a project, but I'm a bit at a loss as to how to actually query for the crate contents</p>

<p>Hi! You probably want to check out <code>CrateDefMap</code> and <code>ImportMap</code> then.</p>

<p>Also, the rust-analyzer team is present in <a class="stream" data-stream-id="185405" href="/#narrow/stream/185405-t-compiler.2Fwg-rls-2.2E0">#t-compiler/wg-rls-2.0</a>, so you might want to ask about rust-analyzer there</p>

<p>hallo, just wondering, who else has ever had a 9 mb hello world 3 liner binary?</p>

<p><span class="user-mention" data-user-id="364811">@pilo chow</span> that's normal, but you're probably building a debug binary, which includes debug info. There are a couple of articles about making Rust binaries smaller, like <a href="https://arusahni.net/blog/2020/03/optimizing-rust-binary-size.html">https://arusahni.net/blog/2020/03/optimizing-rust-binary-size.html</a> or <a href="https://jamesmunns.com/blog/tinyrocket/">https://jamesmunns.com/blog/tinyrocket/</a></p>

<p>My hello world debug binary is 3.1 MB though, while a thin-LTO, stripped, panic="abort" release binary is 259 KB</p>

<p><span class="user-mention" data-user-id="203546">@Laurențiu Nicola</span>  No, even with the --release tag, it still is roughly about that size, maybe it just goes down by  a kilobyte or so, although i did receive feedback from someone, they told me its a known bug on certain platforms,(maybe like mine, Manjaro)that rust will end up compiling all symbols even the 1s i dint use, so yeah, maybe that's why, but thanks a lot for your feedback to, really appreciated<br>
Awesome posts btw, they sure will come in handy</p>
